King's Quest

I recently bought King's Quest 7 and it will not work on my computer. I got KQ 6 to work just fine, so why isn't the later one working? I put the CD in and the I go to my computer and look at Drive F where it has all these icons to chose form. The first time I did it I chose setup and it siad it was installed, but then I couldn't find an icon to let me play the game. Now I can't even get the setup button to work. Does anyone have any advice?
